How Far Can a Dishwasher be From the Sink? Most dishwashers can be placed as far as 12 feet from the sink. This maximum is established by the length of the drain hose that is included with most dishwashers.
Dishwashers should be placed next to the kitchen sink – either on the right or left-hand side – as well as being close to storage units. It is also important to ensure that your dishwasher placement allows freedom of movement.
Can you install a dishwasher anywhere? Within reason, yes. Freestanding models can be installed wherever there's access to a water and drain connection. Integrated models need to be installed in a kitchen cabinet with similar access to a water and drain connection.
use a new drain hose with a maximum length of 12 ft (3.7 m) that meets all current AHAM/IAPMO test standards, is resistant to heat and detergent, and fits the 1" (2.5 cm) drain connector of the dishwasher.
Ideally, it should be located somewhere that makes loading and unloading quick and easy. But it also pays to ensure that your dishwasher door doesn't block any work areas or walkways when it's open. Place it next to the sink. As a kitchen designer, I usually recommend that a dishwasher be positioned next to the sink.
Making Space
Before you can actually install a dishwasher, you first need to check how much space you have with which to work. This allows you to place the dishwasher in the best position. Since you are cutting out existing cabinetry, you'll have to choose a cabinet box to sacrifice for the inclusion of the dishwasher.
If you have the space beside your existing cabinets to place a dishwasher comfortably, then there is nothing stopping you from doing that. All you really need is access to a water line and drain as well as an electrical connection (or the ability to install an electrical connection).
The answer to this question is complicated by the fact that it is much harder to pump water vertically than horizontally. Washing machine manuals typically specify a minimum height of 39” for the entry of the drain hose into the standpipe or faucet box, and a maximum height of 96” (8 feet).
Make sure there is at least 27 inches of open space in front of the dishwasher for loading and unloading.
In terms of convenience and efficiency, this would mean that the dishwasher should be located on the left for a right-handed person. If you are left-handed, the dishwasher should be placed on the right.
Some manufacturers recommend a standpipe, and some water companies insist on it. The easiest solution though, is to put your machine next to a sink and change your sink trap to a washing machine trap – which has an inlet for the waste hose above the trap.
Ultimately, there is no specific place in your kitchen where your washing machine should be stored. So long as you can secure it to the mains it can be placed virtually anywhere.
We strongly recommend you have someone assist you when lifting, tilting and moving your washing machine. Make sure that the drain hose has not been inserted too far into the waste pipe. The maximum should be 15cm inserted, otherwise a vacuum may form which can cause siphonage.
There are two fairly easy ways to fill a gap between the dishwasher and countertop. They are to: Raise the dishwasher's adjustable feet. Elevate the dishwasher with shims, and then cover with a toe plate if necessary.
After Your New Countertops are Installed
For best results, it's generally recommended to wait 24 hours after countertop installation before setting up the sink. (Make sure to have a backup plan to keep your bathroom or kitchen supplied with water for those 24 hours.)
Please note that countertops are usually installed at the end of any remodeling, so if you're purchasing new flooring, appliances or cabinets, those things should be installed first.
If you are designing a kitchen from scratch, it's easy to accommodate for a dishwasher. Leaving a 24-inch opening next to the sink cabinet works in most cases.
A professional can take around an hour to install your dishwasher, as long as no extra kitchen modifications are needed. A DIY job, under the same conditions, would take closer to two or three hours, depending on your level of experience.
The loop should be installed as close as possible to the underside of the cabinet for maximum effectiveness. It is recommended that the discharge end of the drain hose is attached to the vertical sink drain pipe right before the P-trap (never on or after the P-trap).
Air gaps are the most effective means of preventing your drain from cross-contaminating your dishwasher with waste. If you want to protect your dishwasher from flooding with contaminated water, you need an air gap. Dishwasher air gaps are also required by plumbing codes in many locations.
Although new dishwashers come from the manufacturer with the drain looped up at the side of the dishwasher, every installation manual still requires this high loop underneath the sink.
It's not surprising that running waste from your dishwasher and washing machine in the same waste pipe can mean less unsightly pipes leaving your property.
